Looking online I found that you have to add 631065600 to the Garmin timestamp value to get to the UNIX timestamp from which in Excel you can use: The standard UNIX timestamp is the number of seconds since 1st Jan 1970 – approx 1.62 billion today (13th May 2021). Looking now at the timestamps, they appeared to be different from usual. In this way, every row is associated with the most recent timestamp. If the value it contained was a number in excess of 900000000, the cell in the new column took that value, otherwise it took the value of the previous cell from the new column. Each cell in the new column would look at the cell on its row in the TimeStamps column. Next to the table of imported data, I added a column. The timestamps were never on the same row as the heart rate data to which they were associated, so a little data-wrangling was going to be necessary. I selected Combine and Transform, and then used Power Query to delete all but three columns – one column which contained heart rate data, one column which identified when a row contained heart rate data, and one column which contained timestamp data. In Excel I did Data > Get Data > From File > From Folder and browsed to find the directory containing my converted. csv files containing all of the collected WELLNESS data for a particular day. Below show my running a batch file earlier today – not a full day, so only six WELLNESS files.Įxecuting the batch file results in a directory as shown below for yesterday’s data – a collection of. FIT files generated during the day, and the batch file will use FitCSVTool to process each one in turn before dumping them all in a new folder called -CSV.ĭouble-clicking on the batch file will cause it to run, but running it via the command prompt is better when testing so that the terminal output can be read and checked over to ensure that everything seems to be working as expected. csv files into a new directory.īelow is an example of the batch file generated for the watch data collected yesterday (12th May 2021). FIT files from Garmin for a particular day, identify the WELLNESS files I wanted, generate a batch file which when run would convert each WELLNESS file to a. I wrote a rough and ready PHP script to go into the directory of unzipped. Rather than digging around and trying to make sense of the CSV file right away, I decided first to automate the process of converting all of the WELLNESS files for a given day so that I’d have a full day of data to combine and analyse. I opened this in Excel and it looked like quite a complicated mess of data, but I did see references to timestamps, heart_rates, and bpm. FIT files, and a CSV file was output and dumped in the same folder as the original. I wasn’t interested at this time in SLEEP_DATA, so I assumed that the WELLNESS files would contain the heart rate data I was looking for.įollowing the instructions available here:, I processed one of the WELLNESS. There was only one METRICS file, and it was very small. ZIP file when extracted are a collection of files of three types – WELLNESS, METRICS, and SLEEPDATA as pictured below. Clicking on the gear icon (top right) and then on Export Original results in a. Accessing Garmin Connect, I clicked on Health Stats > Heart Rate which brought up the screen as shown below. I downloaded it ( ) and installed everything on my Windows PC.įirst things first, I needed. It is a small part of the Garmin FIT SDK – a software development kit provided by Garmin for developers who need to process. This is a command line tool designed to convert. Searching further online, I stumbled upon FitCSVtool. This works fine for sporting activities such as runs, but it shows all other. FIT files is to import them into Golden Cheetah which is software designed for use by cyclists and triathletes to analyse their training data. These can be copied across to PC via USB from the watch, or exported via Garmin Connect online and downloaded….but how to open and read them? Instead it stores all collected data in proprietary. The watch is a fantastic piece of technology, but there is no way to download the data it collects as a simple CSV or Excel file. The resulting data can be viewed on the associated Garmin mobile phone app and via the Garmin Connect web service. My Garmin Forerunner 245 watch records my heart rate, stress levels, steps, activities, sleep, location, and much more throughout the day.
